This adds the above APIs to the v4l2 core. This is based on version v1.2 of the RFC titled "V4L - Support for video timings at the input/output interface" Following new ioctls are added:- - VIDIOC_ENUM_DV_PRESETS - VIDIOC_S_DV_PRESET - VIDIOC_G_DV_PRESET - VIDIOC_QUERY_DV_PRESET - VIDIOC_S_DV_TIMINGS - VIDIOC_G_DV_TIMINGS Please refer to the RFC for the details. This code was tested using vpfe capture driver on TI's DM365. Following is the test configuration used :- Blu-Ray HD DVD source -> TVP7002 -> DM365 (VPFE) ->DDR A draft version of the TVP7002 driver (currently being reviewed in the mailing list) was used that supports V4L2_DV_1080I60 & V4L2_DV_720P60 presets. A loopback video capture application was used for testing these APIs. This calls following IOCTLS :- - verify the new v4l2_input capabilities flag added - Enumerate available presets using VIDIOC_ENUM_DV_PRESETS - Set one of the supported preset using VIDIOC_S_DV_PRESET - Get current preset using VIDIOC_G_DV_PRESET - Detect current preset using VIDIOC_QUERY_DV_PRESET - Using stub functions in tvp7002, verify VIDIOC_S_DV_TIMINGS and VIDIOC_G_DV_TIMINGS ioctls are received at the sub device. - Tested on 64bit platform by Hans Verkuil Signed-off-by: Muralidharan Karicheri <m-karicheri2@ti.com> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Reviewed-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com> |
